This drawing was my attempt to understand how small changes of the two coordinates can create fluent curves. With the combinations of different lineweights, I was experimenting with the visual depth of different elements. Meanwhile, the three “Taichi” like symbols were inspired by the Sharingan from Naruto which represents creating a world of illusions.
